Zhengwei Wang 96ff0f1e04 drivers: timer: Optimized the ambiq stimer driver 
The original driver has two defects: 1. When setting the next timeout
value the original implementation simply sets a delta value equal to
ticks * CYC_PER_TICK. This operation is reckless and may incorrectly
"reset" the fractional tick, causing clock skew. 2. The original
implementation doesn't handle the counter overflow situation. When the
counter overflows from 0xffffffff to 0x0, the uptimer counter becomes
incorrect. We have fixed above issue by rewriting most of the functions in
this driver and verified it by running all tests under
tests/kernel/timer folder.
